In the original demo I did on the Sensibo Sky aC device (for controlling your Air Conditioner) using the iOS app on my iPhone, I said that the popup controls for accessing Mode (Dry, Cool etc), Fan (fan speed low, high etc), and Temperature (16C and up) on the AC were not accessible if you were using VoiceOver.

with your account email and password, you will get the control screen for your Air Conditioner, and the Popups for Mode, Fan, and Temperature are all accessible as I demo with VoiceOver on iOS and Mac OS.

Climate control is also accessible, but I did not cover this in the demo as I wanted to keep it nice and quick.

Here is the link to the original podcast I did on Sensibo which goes through what it is, setting it up, using the iOS app, and accessing the device from Google Home
